Is the timing chain the same as the timing belt?

Since the inception of the internal combustion engine, one constant has remained – all of them have a timing chain or timing belt. Most higher-displacement engines have a timing chain as opposed to a timing belt.

How is timing advance dependent on distributor speed?

This type of timing advance is also referred to as centrifugal timing advance. The amount of mechanical advance is dependent solely on the speed at which the distributor is rotating. In a 2-stroke engine, this is the same as engine RPM. In a 4-stroke engine, this is half the engine RPM.

When to change ignition timing for maximum power?

Optimum timing from a fixed (locked) ignition advance occurs at only one engine speed. Ignition timing is too advanced at engine speeds below that and not advanced enough at engine speeds above that. Changing the timing value up or down changes the engine speed up or down for the optimum ignition timing.

What do you need to know about timing lights?

You’ll need a timing light. With the light wired up per the instructions and the engine running, point the light at the main pulley that comes off the crankshaft.
